Energy Alert
(by Michael H. Winek, Meredith Odato Graham and Gary E. Steinbauer)
In 2016, U.S. EPA finalized a rule that established first-time federal standards for methane emissions from new, modified and reconstructed sources in the oil and gas industry. The so-called new source performance standards (NSPS) at 40 C.F.R. 60, Subpart OOOOa (Subpart OOOOa) have since become the subject of considerable debate and litigation. Consistent with the Trump administration’s other deregulatory efforts, EPA published a proposal in the Federal Register on October 15, 2018 that aims to reduce the Subpart OOOOa regulatory burden for industry. The agency has already received several comments from concerned citizens who oppose the proposal. EPA will continue to accept stakeholder feedback through mid-December.
Significant Changes to Applicable Requirements
The 52-page rulemaking notice describes several proposed amendments to Subpart OOOOa. EPA is addressing certain issues that were presented to the agency in formal petitions for reconsideration, as well as “other implementation issues and technical corrections” brought to the agency’s attention after Subpart OOOOa was promulgated. For example, it is proposing significant changes to the requirements for fugitive emissions components, including revised leak monitoring frequencies. Whereas the current regulation subjects well sites to semiannual leak monitoring, the revised Subpart OOOOa would require monitoring every other year for low production well sites and annually for all other well sites. The required frequency of compressor station monitoring would be reduced from quarterly to either semiannual or annual. (The proposal includes distinct monitoring requirements for well sites and compressor stations on the Alaska North Slope.) EPA is also proposing to no longer require monitoring surveys at well sites once all major production and processing equipment is removed. These are just a few of the many technical issues for which the agency is seeking public input. …
